Second robot completes survey of Fukushima reactor containment vessel

Japan Nuclear Robot Probe

A second shape-shifting robot completed a survey from inside of the Fukushima Daiichi nuclear Unit 1 in Japan.
 
The second robot was sent into the containment vessel April 15 after the first robot stalled just three hours into its mission five days earlier. The second robot scanned along an approximately 15-meter-long path and measured radiation levels in three locations. The measurements varied from 6.7 sieverts per hour to 8.3 sieverts per hour, according to the Asahi Shimbun.  The first robot had gotten measurements of between 7.0 and 9.7 sieverts per hour in six locations. The readings indicate radiation levels that could kill a human in an hour, the article said.
 
Tokyo Electric Power Co. plans to analyze the footage and readings taken by the robots and use the data when it is time to remove the melted nuclear fuel from inside the building, the article said. Unit 1 was one of three reactors that melted down following an earthquake and tsunami that hit the plant in 2011.
